Summary
Colorectal cancer is the second most commonly diagnosed cancer in Australia, with more than 13500 cases recorded annually. Oxaliplatin is an effective chemotherapy for the treatment of colorectal cancer. The major side-effect of oxaliplatin is the development of nerve damage that leads to loss of feeling in the hands and feet and significant disability. The aim of this study is to conduct a trial of a new treatment for oxaliplatin-induced nerve damage.

Summary
We aim to deliver a radical new precision intervention for peripheral nerve repair to improve the lives of people with peripheral nerve damage. Drawing from our recently awarded work on 'electric neural tissue engineering', we will pre-clinically test our invention of a unique clinically-amenable electric nerve-guide (e-nerve-guide), designed to act as a protective nerve conduit and wirelessly electrically-stimulate damaged nerves for their regeneration and restoration of function.
The Treatment Of BOoking Gestational Diabetes Mellitus Study: The TOBOGM Study

Funding Amount
$2,197,280.00
Summary
Gestational diabetes mellitus (GDM) related pregnancy complications are reduced with treatment from 24-28 weeks pregnant. Many women are diagnosed/treated earlier without evidence of benefit and possible risk of harm. In TOBOGM women under 20 weeks pregnant with mildly raised blood glucose will be allocated by chance to either immediate treatment, or awaiting a repeat diabetes test at 24-28 weeks pregnant to decide treatment. Harmful and beneficial effects on mother and baby will be compared.

Summary
Obesity and diabetes are closely related to these conditions in either parent, but how the father contributes is unclear. We have shown that normal females mated with obese fathers consuming high fat diet, produce offspring who develop glucose intolerance and impaired insulin secretion. This work will examine the mechanisms underlying this effect in the rat, testing a novel role for environmental factors in the father on disease in offspring that may be relevant to the growing obesity epidemic.
Anandamide activated chloride channels in sensory neurons. We are seeking to understand how the nerve cells that sense our environment are regulated by signalling molecules produced by our body. Understanding how these cells function in normal conditions is essential as basis for understanding how they may function abnormally in physically stressful situations or in chronic pain conditions. The work may eventually lead to better treatments for a wide range of disorders that involve the sensory ....Anandamide activated chloride channels in sensory neurons.

Summary
Epilepsy may be due to either one single genetic mutation or a combination of several gene-environment interactions, affecting how ion channels function. It is not possible to directly interrogate channels in the living human brain but, because similar channels are found in peripheral nerve, much may be learned about aberrant channel function from peripheral nerve. This project aims to measure peripheral nerve excitability in epilepsy patients, using it as a marker of the final common pathway of ....Epilepsy may be due to either one single genetic mutation or a combination of several gene-environment interactions, affecting how ion channels function.

The role of intracellular calcium in fibre-type specific gene expression in skeletal muscle. Muscles contain different fibre types whose composition can be changed by activity. The aim of this proposal is to identify the intracellular mechanisms which control fibre type. Our hypothesis is that different patterns of intracellular calcium determine the pattern of gene expression which determines fibre type. Understanding how gene expression is regulated is a central issue in biology.
Peripheral and central mechanisms of sensory coding and integration.

The study of inter-sensory interactions in perception has the potential to be incorporated into the development of virtual reality-type computer-based technologies. The neurophysiology research will provide basic information that has the potential to deepen our understanding, and even enhance possible treatment, of neurological conditions that involve sensory systems.Read moreRead less
Insulin resistance (the inability of ordinarily insulin-sensitive tissues such as muscle and adipose tissue to respond to insulin) contributes to a number of diseases including diabetes and obesity. A key metabolic step in these tissues is the uptake of glucose from the blood stream. This step is accelerated by insulin thus allowing efficient clearance of glucose from the bloodstream after a meal. Our laboratory has played a major role in showing that insulin regulates glucose uptake into muscle ....Insulin resistance (the inability of ordinarily insulin-sensitive tissues such as muscle and adipose tissue to respond to insulin) contributes to a number of diseases including diabetes and obesity. A key metabolic step in these tissues is the uptake of glucose from the blood stream. This step is accelerated by insulin thus allowing efficient clearance of glucose from the bloodstream after a meal. Our laboratory has played a major role in showing that insulin regulates glucose uptake into muscle and adipose tissue by stimulating the movement of a glucose transport protein from inside the cell to the cell surface (see http:--www.imb.uq.edu.au-groups-james-glut4 for an animated description of this process). The purpose of this proposal is to dissect the molecular mechanisms by which this glucose transporter can be held inside the cell in the absence of insulin and then allowed to be released from this site moving to the surface in the presence of insulin. Our studies over the past 5 years have brought us much closer to understanding this process in detail. The identification of the molecules responsible for this regulatory step will not only aid our understanding of this process but it will also provide a valuable target for development of therapeutic agents that can be used to combat insulin resistance.Read moreRead less

Summary
One of the most important evolutionary changes that has occurred is the development of intracellular compartments. All eukaryotic cells possess numerous membrane-encased structures which provide the basis for intracellular specialisation. For example, in order to degrade unwanted components cells have developed degradative enzymes. It is vital for the cell that these enzymes are sequestered away from other cellular components to avoid destruction of valuable molecules. In addition, the cell has ....One of the most important evolutionary changes that has occurred is the development of intracellular compartments. All eukaryotic cells possess numerous membrane-encased structures which provide the basis for intracellular specialisation. For example, in order to degrade unwanted components cells have developed degradative enzymes. It is vital for the cell that these enzymes are sequestered away from other cellular components to avoid destruction of valuable molecules. In addition, the cell has developed a complex assembly line of modifications that are added to proteins in a specific order as they travel to their final destination within the cell. This necessitates the accurate passage of molecules between compartments, a process known as vesicle transport. To orchestrate the complex network of vesicular transport steps between all of the various intracellular compartments it is necessary to employ complex machinery to guide and check that these steps occur with high fidelity. The goal of our research proposal is to define the function of one of the molecules involved in this control process, the so-called Sec1p proteins. The strength of our proposal lies in the diversity of our approach. We intend to explore the molecular advantages of a relatively simple eukaryotic organism, a yeast cell, and apply the findings obtained from this cell to a more complex but highly related vesicular transport process; that of the insulin-regulated movement of a glucose transporter in mammalian fat and muscle cells. While we intend to apply our findings to the treatment of patients with diabetes, it is our ultimate goal to be able to learn more about this fundamental cell biological process so that we can apply our knowledge to understanding many different disease states.Read moreRead less
